Similes and Metaphors (and idioms):
A metaphor is a phrase that states that something IS something else, although it is not actually that thing at all, but used for comparison or to point out attributes.
A simile is a phrase that says something is like something else. It is similar to that thing.
An idiom is a phrase that is commonly used and understood, and may be a simile or a metaphor or just random giberish*, or anything else for that matter. For instance, Red as a Rose, is a simile. Toe headed boy is a metaphor. They are both idioms, as is 'Bob's your uncle', although that is not a metaphor** nor a simile.
*In example: "Blah, blah, blah." Or even "LOL".
**In this case, it is saying something IS something else, but it is not describing any of it's attributes. It is just declaring the project "done".
